Computers & Business Machines

Imagine the loss, 100 years from now, if museums hadn't begun preserving the artifacts of the computer age. The last few decades offer proof positive of why museums must collect continuously—to document technological and social transformations already underway.

The Museum's collections contain mainframes, minicomputers, microcomputers, and handheld devices. A Cray2 supercomputer is part of the collections, along with one of the towers of IBM's Deep Blue, the computer that defeated reigning champion Garry Kasparov in a chess match in 1997. Other artifacts range from personal computers to ENIAC, the Altair, and the Osborne 1. Computer components and peripherals, games, software, manuals, and other documents are part of the collections. Some of the instruments of business include adding machines, calculators, typewriters, dictating machines, fax machines, cash registers, and photocopiers

The Apple Macintosh introduced a graphic user interface (GUI) to the Apple line of computers. The idea had originated at Xerox's Palo Alto Research Center in the 1970s, but Xerox was slow to commercialize it. Apple proved far more successful when it introduced the Macintosh in January 1984, with a splashy television advertisement during the Superbowl. The original price was around $2,500.

Instead of typing out names of programs on command lines, users with a GUI could click "icons," or pictures that represented the programs they wanted to run. They could also execute functions like saving, moving, or deleting files by clicking and dragging the icons around the screen with a pointing device called a mouse. Apple's version of the mouse had a single button, which became an Apple standard. The first Macintosh had only 128K RAM, and users quickly found this insufficient. The Macintosh 512 KB, nicknamed "Fat Mac," was introduced in September 1984. It gave users four times as much memory, and allowed them to keep several major programs open simultaneously. The vertical processor case and 9" monochrome screen were distinguishing features of all the early Macintosh line.

The Macintosh 512 KB contained a Motorola 68000 microprocessor which ran at 8 MHz. It contained 512 KB of RAM and 64 KB of ROM and initially had a 400 KB Floppy disk drive. Applications included MacWrite, a word processor, and MacPaint, a drawing program that turned the mouse into a paintbrush. Shortly after the 512 KB appeared, Apple also introduced a LaserWriter printer, which enabled desktop publishing for individuals and small businesses. Over time, Apple computers would appeal most strongly to artists and designers, while the IBM/DOS line of computers sold better in business markets.

After selling hundreds of thousands of units, Apple discontinued the "Mac Classic" line of computers in April 1986.

This large cash register has a wood and metal exterior painted black, and five columns of keys. The keys in the leftmost column indicate the type of transaction. Right of these keys are four columns of 9 keys, the leftmost for $90 down to $10, the next for $9 to $1, the next for 90 cents to 10 cents, and the last for 9 cents to 1 cent. Hence the machine can have purchases entered of up to $99.99. It is a National model 1852-E, made by National Cash Register Company of Dayton, Ohio. It has serial number 2925055 and dates from 1929.

The paper tape for dispensing receipts is on the left. Above the keys are indicators showing the type of transaction and the amount. A wide cash drawer is at the bottom of the machine. The machine is electrically operated, but there is a place for an operating crank on the right side.

According to the donor, the register was used at Mosely's Jewelry Store on U Street in Washington, D.C. It has an indentation from a 32-caliber bullet, produced in one of the many times the store was robbed. The base price for this machine new was $350.00 in 1927.

This is the oldest surviving example of the type of stepped drum calculating machine constructed under patents obtained by the Frenchman Charles Xavier Thomas of the French town of Colmar in 1820. Machines that could do arithmetic automatically were built as mechanical marvels in the 1600s on the design of mathematicians such as Blaise Pascal and Gottfried Leibniz. However, it was only with the introduction and improvement of the machine of Thomas that calculating machines became part of the world of practical calculation. The instrument was made for Thomas by the Parisian mechanician and clockmaker Devrine. Thomas arithmometers, as the machines were called, became the first commercially successful calculating machines.

The brass machine fits snugly in a wooden case covered with red leather and lined with green velvet. It has three levers that are moved back to enter digits on brass stepped drums. A fourth lever, to the left of these, is labeled Multiplication, and used to determine the number of times the stepped drums rotate. Hence in this early machine, Thomas attempted direct multiplication by a single digit. This feature would not be successfully used in calculating machines until the late 19th century.

In back of the digit levers is a movable carriage with a row of six pairs of windows. Beneath each pair is a button. The levers are labeled: Unités, Dixaines, and Centaines. The pairs of windows are labeled: Unité, Dixaine, Centaine, Mille, Dix Mille, and Cent Mille.

Beneath each window is a numeral wheel. Two sets of digits are marked on each wheel, one in black and the other in red. Shifting a lever on the right of the carriage to “add e multiplication” opens six windows to show in black digits the result of addition and multiplication problems. In the other positions, six windows open to show in red digits the result of division and subtraction problems. Beneath the windows are thumbscrews for zeroing the result digits one at a time. There is no revolution register.

Pulling a red ribbon operates the machine. Pulling a shorter ribbon attached to the front assists in removing it from the case. Later Thomas machines would be crank-operated. The lid of the case has a brass handle, lock, and key. Part of the right side of the case turns down to allow for the motion of the carriage.

A mark on the left of the levers reads: Arithmomètre (/) du Chr. Thomas de Colmar (/) Par Brevet d’invention (/) Devrine fecit. A mark on a button at the front of the machine reads: Régulateur. A mark on the top of the lid reads: ARITHMOMÊTRE (/) De MR. LE CHER THOMAS DE COLMAR.

The machine is not identical to that shown in the drawings of Thomas’s 1820 patent. It resembles the drawings made in 1821 for a report by Hoyau published in 1822.

This gray-green machine has metal exterior and mechanism, and a black plastic plate above the cash drawer, plastic keys and a plastic window. Four columns with nine digit keys each are on the right front and then five columns, each with nine keys, for entering amounts from hundreds of dollars down to cents. Right of these keys are keys indicating types of transactions, as well as TOTAL and SUBTOTAL keys. Right of these is a column of keys labeled with Roman numerals from I to VIII. Next to this are eight windows in a column. Right of these is the operating bar. Indicators are at the top. A space at the front may be meant for a paper tape. The machine has an electric cord, whose measurements are not included in the dimensions. The paper tape is missing.

The machine was made by the National Cash Register Company of Dayton, Ohio in 1943. It is a size 211 (1) and has serial number 4060872. According to a label on the bottom of the cash drawer, it was made for the Mary Webb Beauty Salon on Orange Street in Wilmington, Delaware.

The National Cash Register Company of Dayton, Ohio, expanded rapidly in the late 19th and early 20th centuries. It soon offered not only registers that kept digital records of transactions, but so-called autographic registers that simply allowed one to maintain written records of sales. This example consists of an oak box with a hinged lid, an opening in the lid that reveals a paper tape on which sales may be recorded, and a cash drawer. The decoration at the back of the register, the frame around the paper tape, and the handle on the door are of brass.

The National Size 45 autographic register sold in 1908 for $20.00. For related documentation see 1987.0751.03 and 1987.0751.04.

The McCaskey Credit Register Company of Alliance, Ohio, was in business from 1903 until its acquisition by the Victor Adding Machine Company in 1953. It manufactured a variety of devices to assist in accounting, including this one for keeping track of the accounts of customers.

The instrument is made of ferrous metal, painted black. The outside frame holds eight panels or leaves that rest vertically but may be opened out horizontally. The back of the front leaf and the front of the second are divided to allow an alphabetic index of the later leaves, with small paper slips giving the names of customers and a number for each name. The back of the second leaf, the front and back of the third through seventh leaves, and the front of the eighth leaf are divided into compartments, each of which has a clamp to hold the sales slips in place. These compartments are numbered from 1 to 200. Patent dates listed on the front of the machine range from October 10, 1899, to February 4, 1913.

A mark on the front of the machine reads: The McCASKEY (/) McCASKEY SYSTEMS (/) THE McCASKEY REGISTER CO. (/) ALLIANCE, OHIO. A mark on a metal tab on the borrom of the inside of the front reads: 110831. A mark on a small slip on the first panel reads: 68 - York Springs Fire Co. A mark on a small slip on the second panel reads: Huntington Township. York Springs is a town in Adams County (near Gettysburg), Pennsylvania. The town of Huntington is the county seat of Huntington County, Pennsylvania.

In 1976, computer pioneers Steve Wozniak and Steve Jobs began selling their Apple I computer in kit form to computer stores. A month later, Wozniak was working on a design for an improved version, the Apple II. They demonstrated a prototype in December, and then introduced it to the public in April 1977. The Apple II started the boom in personal computer sales in the late 1970s, and pushed Apple into the lead among personal computer makers.

The Apple II used a MOS 6502 chip for its central processing unit. It came with 4 KB RAM, but could be extended up to 48 KB RAM. It included a BASIC interpreter and could support graphics and a color monitor. External storage was originally on cassette tape, but later Apple introduced an external floppy disk drive. Among the Apple II's most important features were its 8 expansion slots on the motherboard. These allowed hobbyists to add additional cards made by Apple and many other vendors who quickly sprung up. The boards included floppy disk controllers, SCSI cards, video cards, and CP/M or PASCAL emulator cards.

In 1979 Software Arts introduced the first computer spreadsheet, Visicalc for the Apple II. This "killer application" was extremely popular and fostered extensive sales of the Apple II.

The Apple II went through several improvements and upgrades. By 1984, when the Macintosh appeared, over 2 million Apple II computers had been sold.

Exidy, a leading manufacturer of home and arcade video games, introduced its Sorcerer home computer in 1978. The Sorcer used a Z-80 processor that ran at 2.106 MHz and came with 8 KB of RAM, which could be expanded to 32 KB. It ran the CP/M operating system. It sold for $898 with 8 KB of RAM, $1150 with 16 KB of RAM, and $1395 with 32 KB of RAM. It also contained 4 K of ROM. Programs were loaded with plug-in ROM cartridges, and the machine came with a standard BASIC cartridge. This was essentially the common Microsoft BASIC already widely used in the CP/M world. But Exidy added a number of one-stroke commands that allowed users to type in common instructions such as PRINT with a single keystroke. Another popular cartridge contained an early version of the word processor Spellbinder. Users could connect the machine to a standard TV, but the company also offered its own Exidy "Video/Disk" monitor for $2,995.

Judged against its competitors, the Commodore PET and Radio Shack TRS-80, the Sorcerer was comparatively advanced when it appeared. Due to a lack of marketing in the United States, however, it did not sell well there. It did better in Europe and Australia. Exidy took the machine off the market in 1980.

By the late 19th century, many American workers were paid in cash. Putting together packets with precisely the right bills and coins was a tedious task. In the 1890s, Edward J. Brandt, a cashier at the Bank of Watertown in Watertown, Wisconsin, invented a machine that could dispense change automatically.

The machine dispenses change in amounts between 1 cent and 99 cents. It has eight channels across the front, three for pennies, one for nickels, two for dimes, one for quarters and one for 50-cent pieces. Above and behind the channels is an array of 99 plastic keys, numbered from 1 to 99. Pressing another key, marked "5," releases five pennies. On the right are keys marked 10, 25, 25 and 100 that give change for these amounts. The entire coin holder can be removed from the mechanism for storage of coins. Pushing down a key moves a bar that pushes coins from a channel into a compartment with a trap door at its base. Pushing the trap door back releases change into the hand.

A mark on the front and the back of the machine reads reads: BRANDT AUTOMATIC CASHIER. A mark on a brass plate on the back of the machine reads: PATENTED (/) JULY 11, 1899. . . (/) DEC. 12, 1916 (/) 48184 93421 10014 PATENTS PENDING (/) T.M.Reg.U.S.Pat.Off. (/) Brandt Manufacturing Company (/) WATERTOWN, WISCONSIN. The serial number, marked on the right side at the front, is 22446.

Brandt’s machine received medals at the 1900 Universal Exposition in Paris and the 1904 St. Louis World's Fair. This example dates from the 1920s.

This combination adding machine and a cash drawer (AMOD) was made by Sperry Corporation in Searcy, Arkansas. It has four columns of keys for dollars and cents, three additional columns of digit keys, and three columns of keys with various functions on them. An addition bar and cancel button are across the base, and a paper tape at the top. Sales are not displayed visually by any indicator. The metal cash drawer has plastic divisions for change and cash. A key received with the machine controls a lever on the left side.

Marks on the front and back read: Sperry Remington. A mark in marker on the underside reads: 686155. A label attached to the underside reads: MANUFACTURED BY (/) REMINGTON RAND (/) OFFICE MACHINES DIVISION (/) MADE IN SEARCY, ARK.. U.S.A. This label also reads: MODEL 146308-10.

The Remington Rand Division of Sperry Rand Corporation began manufacturing cash registers in 1960, when the corporation acquired the adding machine and cash register division of Clary Corporation, including its factory in Searcy. The form of Sperry Remington trademark on the machine is from about 1968. By 1978, the name of Sperry Rand Corporation had changed because of other mergers, and electronic cash registers were becoming common. For these reasons, the approximate date of the machine is 1970.
